Their Little Secret?

OAK PARK — The May 24 Business story "Wireless satellite achieves orbit" said that, when completed, 66 satellites will comprise the global wireless network called Iridium.

Your readers may be interested to know that iridium is the element that has 77 electrons circulating around the nucleus. The name iridium was selected because the original design of the wireless system called for 77 satellites. Cute. Subsequent revision of the system, however, reduced that number to 66 satellites, and 66 is the atomic number of dysprosium.
